Re: hisense 55K321UW help please

thanks guys , i tried heating up the electrolytic caps on the power board but no change or response , i will take a closer look at the solder joints aswell on the board , frustrating as when i get it to power onn occasionally by the pulling the power cable , holding the power button down for 30 seconds etc etc , sometimes it powers right up and works flawlessly for hours until i switch ot off back to standby , then all i get is the standby light on again , i have noticed the mainboard processor heatsink being warm when testing it , not sure if that...

hi guys , i am looking for assistance with my hisense 55K321UW , stuck on standby , ie light on , but pushing power button has no response , occasionally i can get it to power up and all is perfect until i switch it off again , then only standby light is active and nothing else , internal boards are RSAG7.820 6135 ROH for main board , RSAG7.820 6106 ROH power supply and T-CON is RSAG7.820 6125 ROH , if anyone can give me some directions please post and i will do my best to follow the instructions as well as i can , our local agents cannot supply parts as they say it is discontinued so i am a little...

Hi Guys , i am asking for help with my set please , agents say that no parts are available as it has been discontinued now for a while , the set is just over 6 years old
i will cut to the chase , basically it has RSAG7.820 6135 type main board , 6106 type powersupply and 6137 type t-con board , the standby light is on , psuh the power button and nothing happens , if i disconnect the power supply and hold the power button for 30 seconds etc etc , sometimes it power on right up and will work perfectly again until i switch it off back to standby
I would really appreciate your help...

I have been waiting for a response from our local service centre and finally got a response from them yesterday , unfortunately the reply was that no parts are available due to the set being discontinued , hence me asking now on this site for the kindness of strangers
My 6 odd year old set started not powering up more often than not , standby light on , but 9 times out of ten would do nothing, i tried the whole unplugging the set from the wall and holding the power button down routine and occasionally the set would boot up ok , once alive it worked flawlessly , every aspect worked no problem...
